Original No. 293,538, dated February 12,1834. 1 Application for-reissue siediiisii- 0, 18841 v 1'0 dlZ whom it may concern:

Be it known that LLnsLrn E.SUNDERLAND,

siding at Joliet,in the county of Vill and State of" Illinois, have invented certain new and useful Improvements in Machines for Making Barbed Wire,of which the following is a specification, reference being had therein to the ac com panying drawings.

Figure 1 is a side elevation; Fig. 2, a plan view on the top; Fig. 3, a side view of the coiling-shaft and a front view ofthe cam-wheel that intermittently rotates it; Fig. 4, a crosssection on line 4 ofFig. 3; Fig. 5, a cross-sec tion on lines 1 and 3 of Figs. 1 and 2,showing the barb-wire feed; Fig. 6, a side view of the d-rive-pnlley; Fig. 7,a vertical section of a PUP? tion of Fig. 2 on line 2, looking in. the direction of the arrow; Fig. 8, a rearfview of the reciprocating head 0, which feeds the strand wire W in the machine; Fig. 9,a side view of the spol-olutch S and cross-section of the hollow shaft S to which itis attached ;'-Fig. 10,a

perspective view of afinis'ned barb, being the product of the machine and Fig. 13. a side view of the coiling-shaft set in its boxes and having its reciprocating lever attached.

This machine is for the purpose of manufacturing barbed wire for fencing purposessuch as is. shown in Fig. 12--fornied of a Single strand-wire having crimps at suitable intervals along its length, and having short pieces of wire,pointed at each eud,coiled on the said crimps for barbs, as shown in said figure and to this end my invention and my machine embodying the same consists, in connection with ported on the main frame A, which stands on the coiling head or device for wrapping th barb about the fence-wire, of a pair of crimping jaws or dies to form the crimps or bends in the fence-wire.

Another feature of .theinvention consists in ward. Thisfeature of the invention isofconsider'able advantage in the machine, owing to g the very great: accuracy required in the feed of the fence-wire in order to cause the cross or barb'wire 'to, properly register with the crimps forme'glin the fencewvire. The'invention also consists, in connection with the crimpiugja-ws and a feeding device for the barb-wire, of a guide or device to prevent the fence-wire rotating or turning about its own axis, so that 'the crimps therein may.

be always held and presented to the barb-wire in the same position.

It also consists,in'connection withthe crimp-,

ing dies or jaws and the guide for holding the fence-wire from rotating after the crimps areformed therein,in giving the coiling-head a peculiar longitudinal movement while it is wrapping the barb about the fence-wire, so

that one .coil in the barb will be laid around the fence-wire at one extremity of the crimp, the middle portion of the barb wrapped spirally in the hoilow of the crimp, and another coil in the barb formed at the other extremity -or shoulder of the crimp'.

- It also consists in the particular devices and combination of devices I employ for giving.

the legs A. A centrally-located cross-shaft, S, (shown particularly in Fig. 2,) bears the main drive-pulley B on its outer end, to which the power is applied, and has attached to it all the cams and cranks that drive thevarious parts of the machine, Asprockctwli'eel, d, is attached to the opposite end of said shaft S, and by means of the sprocket:

'chain at drives the sprocket-wheel d on the hollow shaft S upon which the spool W is placed to spool the finished barbed wire. 7 Through the hollow shaft S passes the square shaft S through a square opening at the sprocket wheel end, so that the said square shaft will rotatesaid hollow shaft,and at the same time permit it to slide along back and forth on said square shaft to carry the spool back and forth so the barbed wire will be distributed evenly over its surface.

The sprocket -wheel h on shaft S drives sprocket-wheel h on shaft 01. by means of the sprocket-chain h to drive the wheel a that rofates intennittingly the coiling-head H by means of its meshing with the pinion. m on the part-of the coiling-shaft marked F, as shown in Fig: 11.

The crank P on shaft S is connected by the pitman I to the sliding head K (shown more particularly in Fig. 7) to reciprocate the feedjaws c and c, that grasp the strand-wire W between the dies 0 and 0 and feed it forward into the machine, and at the same time crimp the wire between said dies in the form shown in Fig. 12. I

The waved cam-wheel H on the shaft Soperat-es the die Z,which, in connection with the stationary die Z, cuts off the barbing-wire as 'it is fed in between said dies, as shown in Fig.

5. The die Z is set in the head H, which is pivoted in the frame H by the bolt '1), and which head H terminates in the tail-piece H,

\ having at its. outer end, on the under side, a

pair of wrist-pins and friction-rollers, (shown by the dotted lines in Fig. 2,) between which thewaved cam H rotates to vibrate said tailpiece horizontally to operate said die Z.

The cam D on shaft S operates the feed device that feeds the barb-wire t into the machine. This feed device is shown more particularly in Fig. 5, it being a cross-section on line 3 of Fig.2, looking in the direction of the arrow. The waved cam D rotates between the wrist-rollers D". (Shown in Fig.2 and by the dotted lines in Fig. 5.) Looking at Fig. 5, this feed consists of the vertical arms D and D which stand pivoted at the foot of the hanger D. These two arms are connected at the top by means of the link D and bent l'ever D, having the set-screw n in its outer end. The arm Dhas its upper end terminate in an elbow to sustain the upper set-screw, n directly over set-screw a, be-

tween which set-screws the barb-wire t passes and is grasped tobe fed forward. As cam D rotates between the wrist-rollers D the upper end of arm D oscillates backward and for ward, and by its connection with arm D 0s cilla'tes that in the same manner. As they move forward toward the machine they cause the two set-screw dies n" n to grasp the wire it and drive it forward. The set-screw n passes loosely through an opening through arm D and then screws into the lower side of lever D. \Vhen arm D moves backward, it will carry with it arm D" as soon as the head of W, as shown in Fig. 2.

,must stop long enough to permit the barb to set-screw 92 comes up in contact with arm'D; When set-screw n is. screwed out to 1ts full length, arm D will move some distance before it will move arm -D, and then move it only a short distance, and consequently shorten the stroke of said arm D'and feed -dies a a A longer stroke of feed will be obtained by turning set-screwn in,the length of the stroke of the feed being thus regulated by turning said set-screw in or out. The wire thus fed in forms the barb. The wire is' prevented from being withdrawn by means of the springdog r, pivoted at the side of the frame 1', and held to its work by the spring r". The upper end of the frame 7" overhangs the dog r, so the wire can pass between said dog and said overhanging portion, as shown in. Fig. 5.

The sprocket-chain d drives the spool-shaft S, which is a square rod thatpasses through a square opening through the length of the shaft S ,whi ch rotates in boxes in the frame A". When it is desired to place aspool, W, on the shaft S the shaft S is withdrawn and then passed back through the shaft S and the spool The sprocket-chain d travels or rotates continuously and drives I continuously the sprocket-wheel d on shaft S,

on which it loosely rotates.

The spool can only rotate intermittently to wind on it the finished wire, as the strandwire must stop an instant each time a barb is placed on it, and for that reason the spool be placed on and then rotate sufficiently to take up the wire until it is necessary to stop it to place another barb on it. In order to accomplish this,the sprocket-wheel d on shaft S" is placed between two friction plates or disks, 9 and g, the disk 9 being keyed to the shaft S, so that when it rotates it will rotate the said shaft with it.

The outer end of shaft S is threaded, and a nut, 9 having arms, by means of which it can be turned, is placed thereon, and between said nut and disk 9 is placed a rubber collar, g", and washer 9, so that when the nut g is turned up against said rubber collar it will cause the two disks 9 and g to clamp the sprocket-wheel between them, and clamp it with sufficient force so it will, by frictional contact, rotate with them. Disk 9 being keyed to S rotates that with it, and also the square spool-shaft S upon which the spool'is placed. The frictional contact of the disks 9 and g is not so great but that the barbing part of the machine may hold the strand-wirestill an instant to place on the barb; but it is intended the strand-wi re will only pass through the machine intermittingly asfed in by the reciprocating feed a and c, and that the friction on sprocket-wheel d will not overcome the tension on the said strand-wire at the opposite end of the machine, where it passes betweenthe straightening-jaws 0 0, so that by this means the spool mayrotate intermittingly to take up the finished wire'. The spool must be conveyed on shaft S and rightandthis it is placed on a short hollow shaft, 8,"

left screw S back and forth to distribute the wire over its surface evenly: To accomplish which has a'square hole at one end to sleeve on shaft S. p

The right-and-left screw-shafts has its outer end firmly fixed in theframe A and extends forward so its inner .end meets shaft S within the. sleeved shaft S.

This shaft S has a headyS, integraltherewithmith flanges, between-Which one of the arms of the spool lies, and is held therein by a latch, S. (Shown in Fig. 9.) A switch-S attached to said head S, runs in the screw S and causes the spool to traverse said screw-shaft back and The operation of the machine. js.substan-. tially as follows: The strand-wire?v W enters the machine at the-left, looking at Figs'l and 2, and travels forward in thevdirection of the arrow. It first passes between a pair of dieplates, 0 0, between which itdraws to give tension to the wire as it is drawn through, and also to straighten out any kinks or bends there maybe in it.: The upper die-plate, 0 is set in the arm y, pivoted at its, innerend on the frame 0, whichis partially supported by' the brace 0 while its outer end is held down by the coil-spring y, so as to cause the die-plate 0 to press firmly on the strand-wire. The spring y may be adjusted by means of-the sliding plate 3 to give more or less tension on the arm 3 A weight instead ofsaid spring would answer the purpose as well. The wire Wnext passes into the feed, (shown more particularly in Fig. 7,) consisting of the re ciprocating head 0 and bell-crank jaw c, furnishedwith a pair ofdies,o and 0, regulated by the set-screws c a", and having their meeting-faces formed so that when they grasp the wire they will form-a'bend or crimp-in it,

such as is shown in Fig. 1'2; This reciproeat ing. head is driven by the crank P and pitman P, and traverses in the ways-c c (Shown in Fig. 8.) The head a is divided, as shown in its fear in Fig. 8, so the bell-crank jaw 0- can be pivoted between its two parts,- as shown, and its lower end hangs down, so as to be betweenffthe set-screw Z and the stop Z; made adjustable by the -set-screw Z The stop Z and set-screw Z are attached to a- -head, K,

which reciprocates in ways within said reciprocating head 0, and'to which head the pitman I? is attached, as shown'in Fig. 7. W'hen the pitman moves the head forward, it will cause the stop Z to press against the lower end of the bell-crank jaw c',and by that means move the sliding head 0 forward. A reverse motion causes the set-screw Z" to come in contact.with said jaw, and thus move the head 0 backward. The set-screws Z and Z regulate the distance the head a is to reciprocate, and

thus regulate the distance apart the barbsare grasped between the dies 0 and o and crimped and carriedforward into the stem H., which is provided with a channel its entire length to conduct the wire and hold the crimp right This stem H is shown incrosslargedside view, and isalso shown in Figs. 3

and 4. The part F is the part upon which the pinion m, Fig. 3, is firmly keyed. The remaining portion between said pinion-and the enlarged head end H is inclosed within abox, B,

and is jointed together, as shown in Fig. 11, so the large end H may. be reciprocated horizontally by means of the saddle a, pivoted'to the ears H on the opposite side of the annular ring 11, that lies and turns in a corresponding annular channel in the coiling-head-H This saddle attaches to the lower endof lever a", pivoted near its center in the frame of the machine, while its upper end is provided with. a rollerwrist that runs in the cam-channel a of cam 11. as shown in Fig. 3. This arrangement will givea reciprocating motion to the part F of said coiling-shaft and the head part H having the coilinghook v on its outer end, so that when the coiling-hook 0 begins to coil the barb on the strand-wire it will coil as it recedes, and thus give along coil to the barb to make .it cover the entire crimp in the strand-wire, as shown in Figs. 3, 11, and 12, instead of coiling it all in one place, as'it' would'do if thecoiling-pinion did not reciprocate. The stem H, as before stated, passes through the whole length of the coiling-shaft and is held stationary in the'box a", as shown in Figs. 2

and'3, so. it will not rotate or get out of place, and thus form a. stationary permanent condoctor of the wire W up to the coiling-hook 'v. The coiling-head H rotates in one direction intermittingly, and only rotates'when a barb is to be coiled on. Each feed of the strand -wire delivers a part of the strandwire Vi, where it is crimped directly under the coiling-hook o, as shown in Figs. 3and 1-1, and at the same instant the barb-wire t is fed I in far enough by the barb-feed (described and shown in Fig. 5) to make a single barb, and

at the outer end of the crimp in the strandwire from the coiling-hook o. The coilinghead 11 and the shaft it is attached to then begin to rotate by meansof the teeth m on the pinion m running in the cam-channels a on the face of the cam-wheel a, which causes the coiling-hook v to catch the feed-in end of the barb and coil it on the straud-wi'reW on one of its crimps in the formshcwn in Fig. 12.

The coilingshaft then stops its rotation by means of one of the teeth of the pinion 'm having run into the groove a on the face of the said cam-wheel. As soon as the coiling on of the barb is finished a wave in cam-wheel H- moves the tail-piece H and head -H containing the cutting-off die Z, Fig. 5, and cuts oh the barb from the barb-wire in a diagonal direction, to leave sharp ends for prods. When the head 0 and jaw a move forward,the spool takes up as much finished wire'as is so fed forward by the said head cand jaw 0. .While the bar'bis being socoiled on the strand-wire the reciprocating head a returns to perform anotherlike operation. After a barb has thus been placed on the strand-wire itpasses under a pressto cause the prods of the barb to point in the proper direction and to straighten them. This press is shown in Figs..1 and 7, and consists of the arm B, pivoted at B to the standard H, while its other downwardly-extending end is provided with a roller-wrist to run in the canrchannel of cam-wheel B. The arm B is furnished with the adjustable die It, regulated vertically by the set-screw B. form of the cam-channel in cam-wheel B will cause die R to descend on a barb just at the time it passes under the said die to perform said service.

B isabed-plateoverwhich thewireWpasses, and between which and said die R the barb is so pressed. \Vhen it ascends,itpermits the barb to pass on. The finished barbed wire then passes onto the spool W" over the shoe-guide W", which is' attached to the outer end of the spring-aria W, which is 'for the purpose of preventing a sudden jerk or jar to the spool. As the friction plates or disks heretofore described rotate the spool it draws down on the spring-arm WV, which will give a strain to the wire W, and as said wire is fed forward said spring will ease "the starting of the spool. The barbing-wire after it leaves jaws n andn, Fig. 5, passes'into the tube t, which guides the wire into the cutting-off dies Z and Z. The reciprocating head c is provided with a roller, 0, immediately-*inffiont of thedies o and 0', over which thestrand-wire passes, so as to hold it up and not let it drop when jaw 0 opens. The head a is stopped in its forward movement by the stop chwhich isin= tended to arrest the further movement forward by its engaging with spring 0. (Shown in Fig. 1.) The coiling-shaft H may have two boxes instead of one, and constructed as shown in'Eig. 13, if desired. The drive-pulley B is loose on shaft S, while the inner expansible rim, B, is integral with the hub b, which sleeves on over shaft S, and is firmly keyed thereto. The collars b, b, and b are sleeved on said hub loosely. Collar bhas an outwardly-extending arm, I), which pivots, by means of the standard I)", to the frame A, so it cannot rotate with said hub. The arm 11 is hinged between the meetingends of the expansible rimv B by means of the ears b b, Fig. 6', and itslower end is saddled over the collar b, so it will stand in steps on its sides. Collar b has a lever attached to it, b,, so it can be rotated partially on said hub b. Oollars b and b are provided on their meeting faces with radial vertical offsets, as shown in Fig. 2, so that when collar 1) is partially rofated it will press collar 1) over against collar 1), the effect of which is to press upwardly on arm-b, and thus expand the rim B so that it will have frictional contact with the inner side The of the rim of pulley B?, and by such contact be driven or rotated by pulley .B, and with it the main shaft S, that drives the machine.

In order to operate the barbing part of this machine, it is absolutely necessary that a ,spooling device should be used in connection with it to take up the finished barbed wire and draw the strand-wires in and through the machine. For that reason a spooling device is shown and described; but any other suitableespooling apparatus may be used as well as the one shown.
